When patients visit our office at TMJ & Sleep Centre of San Fernando Valley in Brentwood, California, they often ask about the connection between what they eat and how their body feels. I’m Dr. Farshid Ariz, DMD, a periodontist who sees the effects of chronic inflammation every day — in the gums, the jaw joints, and the surrounding tissues. One of the most empowering steps you can take for your oral and overall health is learning which inflammatory foods may be working against you.
Inflammation is your body’s natural defense system. When you cut your finger, inflammation helps it heal. But when inflammation becomes chronic — lasting weeks, months, or even years — it starts to cause harm. Chronic inflammation has been linked to gum disease, TMJ disorders, poor sleep quality, heart disease, and diabetes. What many people don’t realize is that certain everyday foods can trigger or worsen this chronic inflammatory response.
In this post, I’ll walk you through five common foods that promote inflammation. Understanding these dietary triggers can help you make smarter choices, reduce pain, and support your body’s healing processes.
What Makes a Food Inflammatory?
Before we dive into the list, let’s talk about what actually makes certain foods inflammatory. Foods that promote inflammation typically do so by increasing the production of pro-inflammatory molecules in the body, such as cytokines and C-reactive protein (CRP). They may also disrupt the balance of your gut bacteria, which plays a major role in immune regulation.
According to a landmark study published by the Harvard Medical School, diets high in refined carbohydrates, fried foods, and sugar-sweetened beverages are strongly associated with elevated markers of chronic inflammation. When these foods become staples in your diet, the inflammatory response never fully turns off — and that is when problems arise.
1. Refined Sugar and Sugary Beverages
Refined sugar is one of the most well-known inflammation-triggering foods. Sodas, fruit juices with added sugar, candy, pastries, and many breakfast cereals are loaded with it. When you consume excess sugar, your body produces more cytokines — small proteins that signal your immune system to ramp up inflammation.
A 2014 study published in the American Journal of Clinical Nutrition found that consuming just one or two sugar-sweetened beverages per day increased CRP levels by 20% compared to those who consumed none. That is a significant jump from something many people consider a harmless daily habit.
For my patients in Brentwood and the surrounding San Fernando Valley area, I always recommend reading labels carefully. Sugar hides under many names — high fructose corn syrup, dextrose, maltose, and sucrose are just a few. Cutting back on these foods that cause inflammation can make a noticeable difference in gum health and TMJ symptoms.
2. Processed and Red Meats
Hot dogs, sausages, bacon, deli meats, and even some red meats are classified as foods with inflammatory properties. These products often contain advanced glycation end products (AGEs) — compounds that form when proteins or fats combine with sugars. AGEs trigger an inflammatory response in the body.
The World Health Organization classified processed meats as a Group 1 carcinogen in 2015, and the inflammatory pathways they activate are part of the reason. When you eat these meats regularly, you are essentially feeding the fire of chronic inflammation.
This does not mean you need to eliminate all meat from your diet. Lean, unprocessed options like chicken, turkey, and wild-caught fish are much better choices. Fish, in particular, contains omega-3 fatty acids that actually help reduce inflammation — the opposite effect.
3. Refined Carbohydrates
White bread, white pasta, white rice, and many baked goods are made from refined grains. During the refining process, the fiber and nutrients are stripped away. What remains is essentially a fast-digesting starch that spikes your blood sugar rapidly.
These blood sugar spikes lead to increased insulin production, which in turn promotes the release of pro-inflammatory compounds. Over time, a diet built on refined carbs contributes to insulin resistance — a condition closely tied to chronic inflammation and metabolic disease.
Many of my patients at our Brentwood practice are surprised to learn that their morning bagel or afternoon crackers could be contributing to their jaw pain or gum inflammation. Swapping refined grains for whole grains — like quinoa, brown rice, or whole wheat bread — is a simple change that supports an anti-inflammatory lifestyle.

4. Fried Foods and Trans Fats
French fries, fried chicken, doughnuts, and many fast-food items are cooked in oils that contain trans fats or become oxidized at high temperatures. These damaged fats are among the most potent dietary triggers of inflammation.
Trans fats increase LDL (bad) cholesterol and decrease HDL (good) cholesterol. They also directly stimulate the production of inflammatory markers in the bloodstream. Even though the FDA took steps to ban artificial trans fats in 2018, many fried and packaged foods still contain small amounts that add up over time.
If you enjoy the occasional treat, that is perfectly fine. The goal is not perfection — it is awareness. Knowing that fried foods are inflammation-promoting foods empowers you to make better choices most of the time. Baking, grilling, or air-frying are healthier cooking methods that preserve flavor without the inflammatory cost.
5. Excessive Alcohol
A glass of red wine now and then is unlikely to cause significant issues. However, regular or heavy alcohol consumption is a well-documented driver of chronic inflammation. Alcohol disrupts the gut lining, allowing bacteria and toxins to leak into the bloodstream — a process known as increased intestinal permeability, or “leaky gut.”
This triggers a system-wide inflammatory response. Over time, excessive alcohol intake has been linked to liver inflammation, periodontal disease, and impaired healing after dental procedures. For patients dealing with TMJ disorders or sleep-related breathing issues, alcohol also relaxes the muscles of the airway, potentially worsening symptoms.
I encourage my patients to be mindful of their alcohol intake, especially if they are already managing an inflammatory condition. Moderation is key, and for some individuals, reducing alcohol can bring surprisingly fast improvements in how they feel. You can learn more about the relationship between inflammation and sleep-related issues in our post about sleep apnea treatment.
How Inflammatory Foods Affect Your Oral Health
As a periodontist, I see the consequences of chronic inflammation in the mouth every single day. Inflamed gums, bone loss around teeth, and TMJ flare-ups are all worsened by a diet rich in pro-inflammatory foods. The mouth is not separate from the rest of the body — it is a window into your systemic health.
Periodontal disease, for example, is fundamentally an inflammatory condition. When you consume foods that drive inflammation, you are adding fuel to the disease process. Reducing your intake of these dietary inflammation triggers can complement your professional periodontal care and lead to better outcomes.
Patients who make positive dietary changes often notice less gum bleeding, reduced jaw tension, and even improved sleep. These benefits compound over time, creating a healthier foundation for your entire body.
Simple Swaps for an Anti-Inflammatory Diet
Making changes does not have to be overwhelming. Here are some practical swaps you can start with today:
- Instead of soda — try sparkling water with fresh lemon or berries
- Instead of white bread — choose whole grain or sprouted grain bread
- Instead of processed deli meats — opt for grilled chicken or turkey breast
- Instead of fried snacks — reach for raw nuts, seeds, or baked vegetable chips
- Instead of nightly cocktails — try herbal tea or a small serving of red wine on occasion
These small shifts can dramatically reduce the amount of inflammation-causing foods in your diet. Over weeks and months, the cumulative benefit is substantial.

Frequently Asked Questions
What are the top inflammatory foods I should avoid for better oral health?
The top inflammatory foods to limit include refined sugar, processed meats, refined carbohydrates, fried foods, and excessive alcohol. These foods increase inflammatory markers in the body, which can worsen gum disease, TMJ pain, and slow healing after dental procedures. Reducing these items from your diet supports healthier gums and less jaw inflammation.
Can eating inflammatory foods make my TMJ disorder worse?
Yes, a diet high in inflammation-promoting foods can intensify TMJ symptoms. Chronic inflammation increases pain sensitivity and swelling in the jaw joint. By choosing anti-inflammatory foods like fish, leafy greens, and whole grains, many patients experience a noticeable reduction in TMJ-related discomfort.
How quickly will I notice a difference if I stop eating foods that cause inflammation?
Most people begin to notice improvements within two to four weeks of reducing inflammatory foods in their diet. You may experience less gum bleeding, reduced joint stiffness, and better sleep quality. The timeline varies by individual, but consistency with dietary changes leads to the most significant long-term results.
Is sugar really that bad for inflammation in the body?
Sugar is one of the most potent dietary triggers of chronic inflammation. Studies show that consuming sugar-sweetened beverages daily can raise C-reactive protein levels by 20%, significantly increasing your inflammatory burden. Reducing added sugar is one of the most impactful changes you can make for both oral and systemic health.
What foods should I eat instead to reduce inflammation?
Focus on whole, unprocessed foods such as fatty fish like salmon, fresh fruits and vegetables, nuts, seeds, olive oil, and whole grains. These foods contain antioxidants and omega-3 fatty acids that actively help lower inflammation. Pairing a balanced anti-inflammatory diet with regular dental care creates the best outcomes for your health.
